6 06000 PROFILE GRINDER SAFETY PRECAUTIONS:. ALWAYS WEAR PROTECTIVE EQUIPMENT SUCH AS GLOVES, SAFETY GLASSES, EAR PROTEC- TION, SAFETY SHOES AND OTHER REQUIRED SAFETY EQUIPMENT.. DO NOT WEAR CLOTHING WHICH MAY BECOME ENTANGLED IN THE TOOL. 3. ALWAYS KEEP WORK AREA FREE OF TOOLS OR ANY OTHER OBJECTS WHICH MAY IMPAIR SOUND FOOTING. 4. CAUTION OIL INJECTION HAZARD EXISTS WITH THIS TOOL. OIL INJECTION IS A CONDI- TION WHERE THE HYDRAULIC OIL IS FORCED UNDER THE SKIN THROUGH PRESSURE IN THE LINE. ALWAYS WEAR GLOVES AND REPAIR LEAKS IMMEDIATELY. 5. NEVER CHANGE STONES WITH THE POWER SOURCE VALVE(S) IN THE ON POSITION, TURN THE POWER SOURCE OFF. 6. NEVER ATTEMPT TO CARRY THE GRINDER WITH THE POWER SOURCE VALVE(S) IN THE ON POSITION, TURN THE POWER SOURCE OFF. 7. NEVER TOUCH OR TRY TO STOP A MOVING STONE. 8. ALWAYS CHECK THE WORK AREA FOR ANY TRASH, WHICH MAY IGNITE FROM SPARKS, WELD SPLATTER OR SLAG. 9. ALWAYS CHECK THE AREA FOR SMOLDERING TIES OR TRASH BEFORE LEAVING THE SITE. 0. WHEN CHANGING STONES, FOLLOW ALL GRINDING STONE MANUFACTURES IN- STRUCTIONS FOR SAFETY AND OPERATION. USE ONLY STONES THAT COMPLY WITH ANSI STANDARDS. BEFORE USING, RUN NEW GRINDING STONE FOR ONE MINUTE AT FULL SPEED TO CHECK FOR DEFECTS OR VIBRATION.. MOST HYDRAULIC OILS HAVE A FLASH POINT OF 500 DEGREES (F). MAKE SURE HOSES ARE COMPLETELY CLEAR OF SPARKS AND HOT DEBRIS. HAVE ANOTHER PERSON STAND CLOSE TO HYDRAULIC POWER SOURCE CONTROLS TO OBSERVE OPERATION AND FOR EMER- GENCY SHUTDOWN IF NECESSARY. OPERATIONS:. WITH THE TOOL TURNED OFF, PLACE THE TOOL ON THE RAIL CAREFULLY AND ADJUST THE STONE CLEARANCE BY TURNING THE HAND WHEEL COUNTERCLOCKWISE TO RAISE THE STONE.. WITH THE POWER SOURCE IN THE OFF POSITION, CONNECT THE HOSES. DO NOT DRAG THE SERVICE HOSE BY PULLING WITH THE TOOL. LOOP THE SERVICE HOSE IN THE WORK AREA IN SUCH A WAY TO RELIEVE STRESS ON THE HOSE AND QUICK DISCONNECT (QD) FITTINGS WHILE WORKING. BE AWARE OF HOSE LOCATIONS AT ALL TIMES. CONTINUED ON NEXT PAGE. MATWELD, INC. PHONE:(70) FAX:(70)

7 06000 PROFILE GRINDER 3. CONNECT THE TOOL TO THE POWER SOURCE. 4. TURN POWER SOURCE TO THE ON POSITION TO SUPPLY 0GPM TO THE TOOL. 5. THE NORMAL WORK POSITION IS TO STAND BEHIND THE WORK HANDLE FACING THE HEIGHT ADJUSTMENT WHEEL. IN THIS POSITION YOU WILL SEE THE ON/OFF VALVE (QD FITTINGS ATTACHMENT POINT) ON THE RIGHT END OF THE WORK HANDLE. THE KNOB ON TOP IS TURNED CLOCKWISE TO START THE GRINDER MOTOR. TURN COUNTER CLOCKWISE TO SHUT THE MOTOR OFF. 6. GRASP THE WORK HANDLE FIRMLY BEFORE BEGINNING THE GRINDING OPERATION. BE SURE THE STONE IS BACKED OUT FOR CLEARANCE FROM THE RAIL. WITH THE GRINDER RUNNING, FEATHER THE STONE IN BY SLOWLY TURNING THE HEIGHT ADJUSTMENT HAND WHEEL CLOCKWISE. YOU WILL FEEL THE RESISTANCE AND SEE SPARKS AS THE STONE CONTACTS THE RAIL. 7. ROLL THE GRINDER SIDE TO SIDE TRAVERSING THE SECTION OF RAIL BEING DRESSED A LITTLE AT A TIME. DO NOT ATTEMPT TO REMOVE TOO MUCH MATERIAL IN ONE PASS. KEEP THE TOOL MOVING TO PREVENT BURNING OR OVER GRINDING THE RAIL. SIDE RAIL GRINDING:. THE PROFILE GRINDER CAN BE POSITIONED WITH THE FRAME AND GRINDING HEAD LAID OVER IN A HORIZONTAL PLANE TO ALLOW REMOVAL OF ROLL OVER OR OTHERWISE DRESS- ING THE SIDE OF THE RAIL HEAD.. WITH THE POWER SOURCE TURNED OFF, BACK THE STONE UP COUNTERCLOCKWISE ON THE HEIGHT ADJUSTMENT WHEEL SEVERAL TURNS FOR CLEARANCE. LAY THE GRINDER OVER FROM THE VERTICAL POSITION TO THE HORIZONTAL POSITION. 3. TURN THE POWER ON AND FEATHER THE STONE INTO THE RAIL WHILE ROLLING THE GRINDER IN A SIDE TO SIDE MOTION. DO NOT ATTEMPT TO REMOVE TOO MUCH MATERIAL IN ONE PASS. CHANGING THE GRINDING STONE:. TURN THE POWER SOURCE OFF AND DISCONNECT THE HOSES FROM THE TOOL. LAY THE TOOL ON IT SIDE.. POSITION THE TOOL FOR ACCESS TO THE BOTTOM OF THE CAST ALUMINUM DRIVE HOUSING. 3. LOCK THE DRIVE SHAFT BY DEPRESSING THE LOCKING PIN LOCATED JUST BELOW THE MOTOR ON THE CAST HOUSING. 4. IT IS RECOMMENDED TO UTILIZE A STRAP WRENCH WHEN REMOVING A WORN STONE. AGAIN THE SHAFT LOCK MUST ALSO BE ENGAGED FOR THIS OPERATION. MATWELD, INC. PHONE:(70) FAX:(70)

8 MAINTENANCE:. CHECK TOOL DAILY FOR PROPER OPERATION, LEAKS, OR DAMAGE.. INSPECT HOSES DAILY. REPLACE CUT, BURNED, OR OTHERWISE DAMAGED HOSES. 3. KEEP QUICK DISCONNECT COUPLERS CLEAN AND LUBRICATED. 4. USE HYDRAULIC FLUIDS THAT COMPLY WITH HTMA SPECIFICATION 5.7, THE HYDRAULIC FLUID SHOULD HAVE A VISCOSITY BETWEEN 00 AND 400 SSU (0-8 CENTISTOKES) AT THE MAXI- MUM AND MINIMUM EXPECTED OPERATING TEMPERATURES. PETROLEUM BASED HYDRAULIC FLUIDS WITH ANTI-WEAR PROPERTIES AND A VISCOSITY INDEX OF OVER 40 WORK FOR A WIDE RANGE OF OPERATING CONDITIONS. THE FOLLOWING OILS MEET HTMA SPECIFICATION 5.7: AMOCO RYKON MV CITGO A/W ALL TEMP SUNVIS 706 MOBIL D.T.E. 3 CHEVRON EP-MV TEXACO RANDO HDAZ OTHER FLUIDS THAT MEET OR EXCEED THIS SPECIFICATION CAN BE USED. *SEE COLD WEATHER OPERATION HYDRAULIC OIL NOTE. 5. HAVE TOOL INSPECTED, AT LEAST ANNUALLY, BY MATWELD OR A MATWELD QUALIFIED SER- VICE REPRESENTATIVE TO DETERMINE IF TOOL IS IN NEED OF SAFETY CHANGES OR WORN PART REPLACEMENT. 6. CONTACT MATWELD ON A PERIODIC BASIS, AT LEAST ANNUALLY, FOR SERVICE BULLETINS, SAFETY NOTICES, OR OTHER IMPORTANT INFORMATION PERTAINING TO THIS TOOL. COLD WEATHER OPERATION: HYDRAULIC SYSTEM PERFORMANCE IS AFFECT WHEN THE TEMPERATURE DROPS BELOW 50 F. THEREFORE MEASURES SHOULD BE TAKEN TO PRE-WARM TOOLS AND FLUIDS BEFORE OPERATING. MATWELD, INC. PHONE:(70) FAX:(70)

9 REPAIR AND TROUBLESHOOTING: IF SYMPTOMS OF POOR PERFORMANCE DEVELOP, THE FOLLOWING CHART CAN BE USED AS A GUIDE TO CORRECT THE PROBLEM. WHEN DIAGNOSING PROBLEMS WITH OPERATION OF THE GRINDER, ALWAYS CHECK THAT THE HYDRAULIC POWER SOURCE IS SUPPLYING THE COR- RECT HYDRAULIC FLOW AND PRESSURE, AS LISTED IN THE SPECIFICATIONS. USE A FLOW AND PRESSURE TEST GAUGE TO BE ACCURATE (MATWELD PART NO ). CHECK THE FLOW WITH THE HYDRAULIC OIL TEMPERATURE AT LEAST 80 DEGREE F/7 DEGREE C. PROBLEM CAUSE REMEDY Grinder does not run Grinder operates to slow. Hydraulic power source not functioning.. Couplers or hoses blocked. 3. Hydraulic motor failure. 4. Hydraulic lines not connected. 5. Hydraulic motor speed to slow. 6. High backpressure. 7. Couplers or hoses blocked. 8. Oil to hot (above 40f/60c). 9. Oil to cold (below 60f/6c). 0. Hydraulic motor worn.. Flow control malfunction. See general note above locate and remove restriction inspect and repair connect lines See general note above. Check for back pressure above50 psi 7 bar. See note Turn fan on. See cold weather operation of this manual. Have grinder serviced at authorized service center. Grinder operates to fast.. Flow control malfunction See note. MATWELD, INC. PHONE:(70) FAX:(70)

10 REVIEW OF HYDRAULIC PRINCIPLES A. TOOL CIRCUIT. HYDRAULIC FORMULAS: CID X RPM GPM X PSI GPM = 3 HP = 74 (.85) Example: HP required to deliver 0 GPM at 500 PSI. 0 GPM X 500 PSI = 5000 = 0.3 HP (subtract back pressure for tool HP) Estimated HP delivered by pump or used by tool. PSI GPM 500,000,500,000,500 3, BACK PRESSURE BACK PRESSURE MEASURED AT THE TOOL RETURN PORT MUST NOT EXCEED THE MANUFAC- TURERS BACK PRESSURE RATING. MOST MANUFACTURERS LIST THE MAXIMUM BACK PRES- SURE FOR THEIR HYDRAULIC TOOLS AT 50 PSI. BACK PRESSURE MEASURED ON THE RETURN SIDE OF THE TOOL IS THE FORCE REQUIRED TO GET THE OIL BACK TO THE TANK. IN ALMOST ALL CASES THE LOWER THE BACK PRESSURE THE BETTER THE TOOL PERFORMANCE. FIRST, THE BACK PRESSURE IS SUBTRACTED FROM THE MAXIMUM TOOL PRESSURE TO ARRIVE AT A MAXIMUM TOOL OPERATING PRESSURE. FOR EXAMPLE, TOOLS WITH 000 PSI OPERATING PRESSURE ARE INSTALLED ON A SYSTEM WITH 50 PSI BACK PRESSURE. THIS LEAVES750 PSI AS A MAXIMUM TOOL PRESSURE. IMAGINE A SYSTEM WITH 500 PSI BACK PRESSURE. 000 MINUS 500 PSI BACK PRESSURE LEAVES ONLY 500 PSI FOR THE TOOL. SECOND, TOOLS ARE DE- SIGNED FOR PRESSURE TO BUILD ON THE PRESSURE SIDE OF THE TOOL. IF TOO MUCH PRES- SURE BUILDS ON THE RETURN SIDE, NOT ONLY IS PERFORMANCE EFFECTED, BUT SEALS MAY BLOW. THIS IS WHY IT IS VERY IMPORTANT TO DIRECT THE FLOW INTO THE TOOL CORRECTLY. REVERSING THE HOSES TO TEST MAY RESULT IN BLOWN SEALS, DAMAGE TO THE TOOL, AND PERSONAL INJURY. MATWELD, INC. PHONE:(70) FAX:(70)
